The epitaxial crystallization of syndiotactic polypropylene (sPP) on uniaxially oriented polyethylene (PE) has been investigated by electron microscopy and electron diffraction. It is found that the sPP lamellae grow epitaxially on the PE substrate film with the preference in sPP for the b axis as the fast growth direction. Instead of 50 ° as in the system of isotactic polypropylene with PE, the molecular chains of the sPP crystals are ~ _+ 37 ° inclined to the chain direction of PE
